SEPARABLE FLOORING, BOARDED CEILING, ORTHE-LIKE.

SPECIFICATION formingpart of Letters Patent No. 735,969, dated. August11,1903.

Application filed December 28,1901. Seria1No.87,548. (No model-l [Ouseful improvements in flooring and ceiling construction, the same beingformed in sections which are keyed together.

In the accompanying drawings, Figure 1 is a fragmentary verticalcross-sectional view portion of my improvement. Fig. 2 is a modificationthereof. Figs. 3, 4, 5, and 6 are detail views of the respective clamps.Fig. 7 is a view in perspective of one of the boards or panels. Fig. 8is a plan view, partly in section, of a portion of the flooring orceiling constructed in accordance with my improvement. Fig. 9 is a viewin perspective of a modified form of board or panel; and Fig. 10 is aplan view, partly in section, of a portion of the flooring or ceiling inwhich the modified form of panel is shown in position.

It indicates one of the girdersor I-beamsand g the joists supportedthereon. These joists.

are clamped to the girders by means of clamps Z, which have their upperends provided with securing-nuts 0, and being mounted or supported inbrackets 'n, which are driven for a portion of their lengths into thejoists. The lower ends m of these clamps are hooked, so

3,5 as to embrace the, top flange of the girders,

which in Fig. l, as heretofore stated, are I beams. In Fig. 2, however,I have shown an ordinary wooden girder into which the hooked ends m ofthe clamps are driven.

windicates the keys of my improvement, which comprise longitudinalstrips formed on their edges with tongues 6. These strips are secured tothe joists, as by screws.

0 indicates leveling-blocks for ranging the keys whentheir bases areirregular.

a indicates the boards or panels, which are formed on one of their longedges with tongues c and on their opposite edges with grooves, wherebythe series of panels will interlock and form neat joints. The ends ofthese panels are also grooved, as at b, to receive the tongues e of thekeys, which are spaced apart at suitable distances throughout the widthof the flooring or ceiling, as, the case might be. The keys are providedwith a removable section to, and in operation these sections at areremoved and the panels Ct inserted through the spaces occupied therebyand slid along on the tongues a, so as to form a complete row.

In Fig. 2 I have shown the key a: formed in its long edges with tonguesf and'grooves c. This construction is preferred in certainconstructions, inasmuch as the upper faces of the panels are caused tolie flush with the upper edges of the keys, 'and their ends are thusmore fully protected from wear.

In lieu of providing the keys as with removable sections 00 I have inFig. 9 shown a panel in which this construction is dispensed with. Thekeys when this panel is employed have their ribs provided with cutoutportions, through which the respective panels are inserted.

The last'panel a (indicated in Fig. 9) when inserted in position issecured: by a screw 8 or the like, which passes through its and means topermit of the insertion and removal of the panels from said keys,substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand thisl ith day of December, 1901.

PAUL BLAISE GUILHOU.
